@JoeFranz It is probably because of the current firmware 5.15
With
rpi-update b976c54917e240630c05a9b383010f1492bc61b4
I installed version 5.10. It now works again with the standby on the HDMI connection.

@sdetweil The mirror lives again!! Thank you! 
There are still errors in two modules, soccer-live-score and newsfeed
I’ll take a look at that tomorrow
Good job thanks
@sdetweil Ok, I managed it
Now everything is working again as it was before the update, thank you again

@sdetweil ok, that worked now, my mistake 
I also made updates for the pi, unfortunately I now also have the latest firmware version: 82f3750a65fadae9a38077e3c2e217ad158c8d54 from March 2023. I’ve had that before, so the monitor on the pi doesn’t go into standby. I now need to downgrade the firmware to version 5.10 (b976c54917e240630c05a9b383010f1492bc61b4). When I try with “sudo rpi-update b976c54917e240630c05a9b383010f1492bc61b4” it says that the firmware is already up to date.
@sdetweil I renamed the folder and reinstalled the module, this is the result:

Thanks to the great help from @sdetweil, my MagicMirror is now running again after the last update. I was able to fix problems with two modules myself. I just can’t get the MMM PIR sensor module to work. I tried this, and so far it has always worked after an update. Unfortunately not now…
cd ~/MagicMirror/modules
cd MMM PIR sensor
npm i magicmirror rebuild
./node_modules/.bin/MagicMirror-rebuild
Anyone an idea?
Greetings Jörg
